如何在烧瓶中显示目录中的所有图像 [英] How to display all images in a directory with flask
问题描述
我正在尝试以静态(静态/图形)显示特定目录中的所有图像.这是我的python:
I am trying to display all images from a particular directory in static (static/plots). Here is my python:
hists = os.listdir('static/plots')
hists = ['plots/' + file for file in hists]
return render_template('report.html', hists = hists)
和我的html:
<!DOCTYPE=html>
<html>
<head>
<title>
Store Report
</title>
</head>
<body>
{{first_event}} to {{second_event}}
{% for hist in hists %}
<img src="{{url_for('static', filename='{{hist}}')}}" alt="{{hist}}">
{% endfor %}
</body>
</html>`
并且当模板成功渲染时，不会获取模板.在新选项卡中打开图像将产生:
http://127.0.0.1:8080/static/%7B%7Bhist%7D%7D
And when the template successfully renders, the templates are not fetched. Opening the image in a new tab yields:
http://127.0.0.1:8080/static/%7B%7Bhist%7D%7D
我想问题出在这行上，但是我不知道正确的地方是什么:
I imagine the problem is with this line, but I can't figure out what's correct:
<img src="{{url_for('static', filename='{{hist}}')}}" alt="{{hist}}">
推荐答案
尝试将行更改为此:
<img src="{{url_for('static', filename=hist)}}" alt="{{hist}}">
您在其中还有一组{{ }}，它们分别渲染为%7B和%7D.
You had an extra set of {{ }} in there which was rendering as %7B and %7D.
